Environmental monitoring sensors from
Cornwall
An exclusive Processingtalk article from Partech Instruments describes a detector for oil films on water, just one of the environmental monitoring systems developed by this Cornish company
Partech Instruments is a specialist supplier of analysers and instruments for monitoring and control in wastewater, drinking water, industrial effluent and surface water applications Partech is based in Charlestown, near St Austell in Cornwall, close to the picturesque harbour

This year Control Engineering magazine in the USA celebrates its fiftieth anniversary: Michael Babb, the Editor of Control Engineering Europe, reviews what has happened over these 50 years
It must be the scenery there that has led Partech to develop from producing mainly sewage treatment sludge sensors, into clean water and environmental sensors, with the WaterWatch range of water quality and pollution systems.
This Processingtalk Exclusive article (Ref 1) describes the application of a floating infra-red reflectance sensor to detect any oil films visible oil on the discharge water surface, in this case from a power station run by npower at Little Barford, near Cambridge.
Naturally the plant has extensive water discharge monitoring systems, after the water treatment systems and oil interceptors: the Partech WaterWatch is used as a continuous final inspection and alarm system, which makes the power station operations staff immediately aware of any problem before any riverside dog walkers or neighbours start to complain.
They can stop the discharge system while the problem is investigated.
Interestingly one of the slight problems with the system at first was the triggering of the alarm when it saw fish break the water surface within the inspected area in the discharge culvert, but some fine tuning from Partech has solved such natural false alarms.
Other similar monitoring projects reported on Processingtalk by Partech have related to monitoring the rivers in Devon and Cornwall, such as the Red River, contaminated for so long with minerals from the local tin mining industry, that it was classified as an industrial drain until the 1960s.
Now, as part of the EU funded Cycleau Project, the Red River is the subject of a new approach to the passive treatment of metal contaminated watercourses, and uses several styles of sensor from Partech to monitor the water condition (Ref 2).
